When the temperature measuring element 341 leaks electricity, the controlled switch 371 is turned on to power off the load driving circuit 35. By such arrangement, the load driving circuit 35 can be turned off from the hardware when the temperature measuring element 341 leaks electricity, so that the leakage protection circuit 37 can more effectively turn off the load driving circuit 35, thereby greatly improving the safety.

In some embodiments, the food processor circuit 30 includes a ground 372, the ground 372 is connected to the second power input 32, and the controlled switch 371 is connected between the load drive circuit 35 and the ground 372. So set up, after controlled switch 371 receives the high-voltage signal of the second end 343 of temperature measurement component 341 and switches on, load drive circuit 35 and ground terminal 372 turn off after being connected directly to play the effect of turning off load 38, protecting other components in the material reason machine circuit 30, ground terminal 372 sets up and makes earth leakage protection lower cost and high efficiency, and makes the circuit setting simple.

In some embodiments, the load driving circuit 35 includes a driving element 352 and a transistor Q1, where the driving element 352 is connected to the load, and the driving element 352 is controlled by the controller 36 to be turned on or off so as to drive the load. The base of the triode Q1 is connected with the control terminal 361 and the controlled switch 371, the collector of the triode Q1 is connected with the driving piece 352, and the emitter of the triode Q1 is connected with the grounding terminal 372.

So configured, the drive control for the load 38 is more accurate.

The base of the triode Q1 is connected with the controlled switch 371, when the temperature measuring element 341 leaks electricity, the controlled switch 371 is turned on, the base of the triode Q1 is grounded, the triode Q1 is turned off, and the load driving circuit 35 is turned off, so that the effect of turning off the load 38 and protecting other elements in the material processing circuit 30 through hardware setting is achieved, and the leakage protection circuit 37 is simpler and more efficient.

In some embodiments, the load driving circuit 35 further includes an optocoupler 351, and the optocoupler 351 is connected between the driver 352 and the transistor Q1. By means of the arrangement, electric isolation can be achieved through the optocoupler, high-voltage alternating current is prevented from being directly contacted with a circuit (such as the temperature detection circuit 34), and accordingly personal safety of a user of the food processing machine 1 and stability of the food processing machine 1 are guaranteed.

As shown in fig. 3, in some embodiments, the load 38 of the food processor 1 includes a heat generating component 382 and a motor 381, and the load driving circuit 35 includes a load switching circuit 353, and the load switching circuit 353 is connected to the driving member 352, the heat generating component 382, and the motor 381. The motor 381 drives the blades of the food processor 1 to cut and stir food materials in the food processing cup 20. Heat generating component 382 controller 36 is coupled to load switching circuit 353 for controlling the switching of load switching circuit 353 between heat generating component 382 and motor 381. In some embodiments, load switching circuit 353 includes a power switching relay 354. The controller 36 may control the on/off of the electromagnetic coil of the power switching relay 354 so that one of the heat generating component 382 or the motor 381 may be connected to the driving member 352, thus providing the effect that one load switching circuit 353 may control a plurality of loads 38.

In some embodiments, the leakage protection circuit 37 further includes a zener diode D601, wherein an anode of the zener diode D601 is connected to the controlled terminal 3711 and a cathode is connected to the second terminal 343 of the temperature measuring element 341. When zener diode D601 is in the normal operating region, it will operate at a fixed reverse bias voltage. When the high voltage ac enters the temperature measuring element 341, the input voltage exceeds the breakdown voltage of the zener diode D601, and the zener diode D601 enters the breakdown voltage state. In this case, the zener diode D601 may guide the excessive voltage to the ground, which serves as other elements of the food processor circuit 30 from being damaged by the excessive voltage. By selecting the proper type and breakdown voltage of the zener diode D601, the zener diode D601 can be made to act as an overvoltage protection device in the food processor circuit 30. So set up, set up dual earth leakage protection for earth leakage protection circuit 37, improved earth leakage protection circuit 37's stability and reliability, protected other components in the cooking machine circuit 30, strengthened the security of cooking machine circuit 30.

The zener diode D601 has a lower internal resistance, and when the current is larger, the zener resistor R1 needs to be added to limit the current, otherwise, the problems of overheating and damage of the zener diode D601 easily occur, and meanwhile, the output voltage of the zener diode D601 is also caused to lose stability. Thus, the voltage stabilizing resistor R1 can perform a current limiting function, prevent the voltage stabilizing diode D601 from being damaged by excessive current, and increase the stability and reliability of the leakage protection circuit 37.

In some embodiments, the temperature detection circuit 34 further includes a first resistor R2, a second resistor R3, and a dc power supply terminal 344, the first resistor R2 is connected between the dc power supply terminal 344 and the second terminal 343 of the temperature measurement element 341, one end of the second resistor R3 is connected between the first resistor R2 and the second terminal 343 of the temperature measurement element 341, and the other end of the second resistor R3 is connected to the detection terminal 362 of the controller 36. So configured, the accuracy of temperature detection may be increased while providing over-current protection for the temperature detection circuit 34.

When electric leakage occurs in the cup coupler 33, high-voltage alternating current flows through the food processing circuit 30 via the temperature measuring element 341, and the high-voltage alternating current flows into the electric leakage protection circuit 37 from the second end 343 of the temperature measuring element 341, so that the controlled switch 371 is turned on, and the controlled switch 371 is connected with the grounding end 372 and the load driving circuit 35 is connected with the control end 361. Therefore, after the controlled switch 371 is turned on, the transistor Q1 in the load driving circuit 35 is grounded and turned off, the driving element 352 connected to the transistor Q1 is turned off, and the load driving circuit 35 no longer drives the load 38. And the control terminal 361 is pulled down until the control terminal 361 is low, in some embodiments, after which the control terminal 361 is low the controller 36 is reset and the controller 36 can control the load driving circuit 35 to drive the load 38 on the next cycle of ac power.

The zener diode D601 and the zener resistor R1 are connected between the controlled terminal 3711 and the second terminal 343 of the temperature measuring element 341, so that not only can the low voltage of the dc power supply terminal 344 be isolated, but also the generated high voltage ac can be subjected to leakage protection when the temperature measuring element 341 leaks. By arranging the circuit of any one of the embodiments in the food processor 1, the food processor 1 is safe and durable.
